IMPROVEMENT IN HANKS FOR JIBS, 84c.

Specification forming part of Letters Patent No. 134,164, dated December24, 18?2.

To all whom it may concern:

Be it known that I, WILLIAM A. PRATT, of Deep River, in the county ofMiddlesex and State of Connecticut, have invented certain new and usefulImprovements in Hanks for Jib and Stay Sails, of which the following isa specification, reference being had to the accompanying drawing, inwhich- Figure 1 is a side view of the complete hank. Fig. 2 is a topview of the same. Fig. 3 is a view of the hank applied to a jib andstay.

The common hank consists of two metal rings, one larger than the other,united together, the larger running on the stay-rope, and the smallerfastened to the edge of the sail bymarline or seizing running throughthe smaller ring, and a hole near the edge of the sail called a grommet.When the sail is taken off the stay or unbent, as the sailors call it,the marline has to be cut, thus rendering it useless. When the sail isagain bent to the stay the hanks have all to be lashed on again,

at a considerable expense of the marline and of time.

By means of my invention the sail can be bent and unbent in a shorttime, and without cutting the marline.

The letter A indicates a metal ring, which slides on the stay-rope,having the hook a, the whole of which I denominate a hooked ring.

The letter B indicates a piece of metal having the concave seat 12, soas to partially embrace the luff-rope at the edge of the sail, the ring,

b into which takes the hook a, and also the tongue D which prevents thehook from slipping out of the ring by accident, the whole of which Idenominate the hank-base. This hankbase is fastened to the sail C by alashing, (I, called marline or seizing, running around the hank-basethrough the ring b and the grommet f.

When the sail is to be unbent the hooks to are slipped out of the ringsb and when the sail is to be bent the hooks are slipped in again. Thetongue 11 prevents the hook from coming out until the ring A is turnedup at an angle which it cannot attain except by the aid of a personshand.

I claim as my invention-- 1. The hank-base, provided with the ring D andthe underlying tongue b constructed substantially as described.

The combination of the hank-base, pro vided with such ring and tongue,with the hooked ring A, the whole arranged substantially as described.
